I'm developing a port program for Bill Service's Bonneville effort (50 Plymouth Business Coupe). The head R&D work is nearly complete and we are looking for other parties interested in getting some heads done. We are using the 1956 #049 casting to accomish this. The head is currently flowing over 300cfm with a 1.96 intake valve. Would like to get some more interest to help keep the CNC machining costs down and do a small run of them (3-4 sets). If anyone is interested please contact me.
